The present invention relates to a method of treating or preventing hair loss or excessive hair shedding in a subject by administering to a subject an oral dose of minoxidil. In particular, the present invention relates to a method of treating telogen effluvium in a subject by administering to a subject an oral dose of minoxidil.

Technical Field
The present invention relates to detection and treatment of hair loss or excessive hair shedding. In one aspect, the present invention relates to treatment of telogen effluvium. The present invention also relates to a visual analogue scale for determining hair loss or excessive hair shedding.

Background
Hair follicles on the scalp do not continuously produce hair. They cycle through a growth stage that can last two or more years, then regress to a resting stage for up to two months before starting to grow a new hair fiber again. At any time on a healthy human scalp, about 80% to 90% of the hair follicles are growing hair. These active follicles are in what is called the anagen phase. That leaves up to 10% to 20% percent of scalp hair follicles in a resting state called telogen, when they don't produce any hair fiber. Changes in actual amount of hair fall occur in number of hair loss conditions including anagen effluvium, acute and chronic telogen effluvium, alopecia areata, cicatricial alopecia, male pattern hair loss (MPHL) and female pattern hair loss (FPHL).
Men commonly complain of increased hair loss or hair shedding, especially after washing their hair. Changes in actual amount of hair fall occur in number of hair loss conditions including anagen effluvium, acute and chronic telogen effluvium, alopecia areata, cicatricial alopecia and male pattern hair loss (MPHL).
Female pattern hair loss (FPHL) is the most common cause of hair loss encountered in clinical practice for women (Messenger et al. 2010). FPHL is a complex polygenic disorder characterised clinically by diffuse hair thinning over the mid frontal scalp and histologically by hair follicle miniaturization. The proportion of miniaturized follicles increases with the severity of hair loss (Messenger et al. 2006). FPHL adversely impacts quality of life and the prevalence of FPHL increases with age. In a population study of over 700 women, FPHL was found in 12% of women aged 20-29 and 57% of women aged > 80. Hair loss severity also increases with age.
One such condition that results in in increased hair loss or excessive hair shedding is telogen effluvium (TE). This condition effects both men and women, occurring more commonly in women. TE is a non-scarring alopecia characterised by excessive shedding of telogen club hair diffusely from the scalp. It generally begins 8-12 weeks after a triggering event such as pregnancy, major illness or complicated surgery and is resolves within 3-6 months. Once resolved, self-limiting telogen effluvium can be retrospectively diagnosed as acute telogen effluvium (Harrison S and Sinclair R, 2002). Telogen shedding that persists beyond 6 months is called chronic telogen effluvium (CTE) (Whiting, DA 1996). CTE may be primary or secondary to a range of triggers including androgenetic alopecia (AGA), nutritional deficiency, endocrinopathy, connective tissue disease or drug induced (Messenger et al., 2010).
The aetiology of primary CTE is unknown (Whiting, DA 1996). The natural history is for continued hair shedding over many years. Long-term follow up studies of women with primary CTE (Bittencourt C, 2014) and histomorphometric and immunohistochemical examination of scalp biopsies in patients with both FPHL and CTE have confirmed that primary CTE is not a prodrome to AGA (Whiting DA, 1996).
Primary CTE most commonly occurs suddenly in females between 30 and 50 years of age. Additional clinical features commonly seen in primary CTE include bitemporal recession of the anterior hairline, a reduction in the thickness of their ponytail diameter (Whiting, DA 1996) and trichodynia (Kivanç-Altunay, İ. et al. 2003). Widening of the central part line suggests AGA and is not a feature of primary CTE. Other than identification and treatment of a triggering event such as hypothyroidism, there is no known treatment for acute telogen effluvium (ATE) or CTE (Garcia-Hernandez MJ et al. 1999). Treatments commonly used for AGA such as finasteride, cyproterone acetate, spironolactone and flutamide do not work in TE (Messenger A et al. 2010). Currently, the only suggested treatment for CTE is topical minoxidil, however results are variable and often disappointing. One study demonstrated an improvement in 55.2% of patients studied, using 5% topical minoxidil for men and 5% topical minoxidil with 50 mg of cyproterone acetate for women (Garcia-Hernandez et al. 1999). Only 25.2% of patients had a moderate response to treatment (Garcia-Hernandez et al. 1999). There are currently no FDA or TGA treatments available for chronic telogen effluvium.
There is a requirement for new treatments for conditions of hair loss and excessive hair shedding for both men and women, including telogen effluvium. There is also a requirement for rapid, inexpensive and simple tools for monitoring excessive hair shedding.

Summary
Research described herein has led to the unexpected finding that hair loss or excessive hair shedding can be effectively treated by a daily low dose of oral minoxidil. Related research has also led to the unexpected finding that telogen effluvium, a scalp disorder characterized by the thinning or shedding of hair resulting from the early entry of hair in the telogen phase (the resting phase of the hair follicle), can be treated with oral minoxidil. Further, it has been found that administration of a pharmaceutical salt concentration with oral minoxidil has a an advantageous effect on blood pressure. Further, a novel visual analogue scale for assessment of hair loss or hair shedding has been developed. This scale defines normal hair shedding as well as the range of hair shedding seen in female pattern hair loss (FPHL) and therefore enables diagnosis of women who have hair loss or excess hair shedding. This visual analogue scale has facilitated the assessment of hair shedding in normal conditions and conditions of hair loss.

The methods described herein are relevant to the detection and/or treatment of "hair loss". One particular form of "hair loss" is "hair shedding" described as where hair falls out from skin areas where it is usually present, such as the scalp. Hair shedding can be described as either normal levels of hair shedding or excessive levels of hair shedding. The present disclosure provides a tool and method for characterizing hair loss as normal or excessive. Excessive hair loss or hair shedding may be a consequence of one of the following conditions: alopecia areata, androgenetic alopecia, telogen effluvium (chronic and acute), anagen effluvium, male pattern baldness, female pattern baldness, thyroid problems, monilethrix, anaemia, congenital hypotrichosis, short anagen syndrome, loose anagen syndrome, drug induced and chemotherapy induced hair loss, cicatricial alopecia (lichen planopilaris, discoid lupus erythematosus, folliculitis decalvans), congenital hypotrichosis, polycystic ovary syndrome or malnutrition.

As described herein, the composition is administered "orally", and is thus formulated in a form suitable for oral administration, i.e., as a solid or a liquid preparation. Suitable solid oral formulations include tablets, capsules, pills, granules, pellets, powders, and the like. Suitable liquid oral formulations include solutions, suspensions, dispersions, emulsions, foams, gels, oils and the like. In a preferred embodiment, the composition of this invention is a solid dosage form.
As described herein, the visual analogue scale can be used for assessing daily levels of hair loss or hair shedding. The visual analogue scale comprises a plurality of images on an individual page (or screen) or separate page (or screen) wherein each image displays a bundle of hair representative of a level of hair shedding. The visual analogue scale can comprise images representative of a normal level and/or an excessive level of hair shedding. Images may represent normal hair shedding levels, for example, (i) an image of a bundle of about 5 to 25 hairs; (ii) an image of a bundle of about 25 to 75 hairs; (iii) an image of a bundle of about 75 to 150 hairs; and/or may represent excessive hair shedding levels, for example, (i) an image of a bundle of about 300 to 750 hairs; (ii) an image of a bundle of about 500 to 1000 hairs. The visual analogue scale is suitable for at home use or use by a subject or in the clinical setting by clinicians. A subject or a clinician can use the scale to determine if the daily level of hair shedding is a normal or excessive level of hair shedding by visually determining if the amount of hair shed daily, or on an average day, corresponds to an image representative of normal or excessive daily hair shedding. The visual analogue scale can therefore be used daily, or on alternative days, or several days a week, or once a week or bi-weekly to assess hair shedding. Alternatively, the visual analogue scale may be used by a clinician to assess hair shedding at scheduled appointments for a subject. The visual analogue scale can be used to determine if hair shedding is increasing or decreasing in response to a particular treatment regimen and/or for the diagnosis of a hair loss condition. Additionally, the visual analogue scale may be used in combination with a questionnaire and or other diagnostics for diagnosing a hair loss or excessive hair shedding condition.

Example 1

Methods
Visual analogue scale: long, black/brown club hairs shed from a woman with FPHL was counted and separated into 6 bundles comprising 10, 50, 100, 200, 400 or 750 hairs. The bundles were photographed and were arranged order of size to develop a visual analogue scale shown in Figure 1. The scale was piloted for usability as a hair loss assessment tool in a hair loss clinic. Test-test reliability was defined by scoring women again after 2 weeks. Hair shedding scores were subsequently obtained from women newly diagnosed with female pattern hair loss (FPHL). Normal shedding was defined among adolescent school girls.
In order to assess observer reliability of the hair shedding scale, 50 women attending a hair loss clinic for scalp biopsy were asked to look at an A4 page containing the 6 photos of hair bundles. The women were asked to point to the photograph that best correlates with the amount of hair that would be shed on a wash day, and which photo correlates best with the amount shed on a non-wash day. The frequency of hair washing was also recorded. The results were scored 1-6. When they returned 2 weeks later for removal of their sutures they were again shown the visual analogue scale and asked the same questions.
Female Pattern Hair Loss Group: Women newly diagnosed clinically with FPHL and/or histologically with androgenetic alopecia attending a specialist hair loss clinic were asked to score hair shedding using the visual analogue hair shedding scale. Women already taking oral antiandrogen treatment or using topical minoxidil were excluded. Only women with long or shoulder length hair were included.
Control group: As part of a school science project, 100 girls with straight long hair (below shoulder length) aged 11-15 years were shown the photographs and asked the same questions.

Results
Fifty women with FPHL were enrolled in the pilot study. Hair length was recorded as short, shoulder length or long. Scores at weeks 2 agreed with the scores at week 0 for 46 out of 50 women. Scores disagreed by 1 grade in 4 women. Of these four women all 4 had short hair. In all 4 cases where there was disagreement with the original score, the difference was only 1 grade. Two women increased their score and 2 women decreased their score. The correlation coefficient (r) was 0.98 and the coefficient of determination (r^2) was 0.96 indicating strong correlation (Table 1).

As the photographs were bundles of long hair, and women with short hair had greater difficulty using the chart to score their hair shedding (and due to current fashion trends there were very few school girls to be found with short or shoulder length in the control group), FPHL patients with short or shoulder length hair were excluded from further analysis.
Female Pattern Hair Loss Group: Over a 52 week period scores were obtained from 209 consecutive women with previously untreated female pattern hair loss. The mean age was 46.3 years.
Among the 209 women with long hair, shedding was scored as: grade 6 in 93; grade 5 in 49; grade 4 in 40; grade 3 in 20; grade 2 in 6 and grade 1 in 1 woman. The mean shedding score was 4.93. Results are shown in Table 2.
Control Group: 100 school girls with a mean age of 13.51 years participated in the study. All had long hair. No girls with shoulder length or short hair were interviewed.
Scores are shown in Table 2. While androgenetic hair loss is reported in this age group , it is rare and this data was used as normal control. 99 girls had ≤ grade 4 shedding. Only 1 girl had grade 5 shedding. No girl had grade 6 shedding. The mean hair shedding score was 2.68, which is significantly less than the mean shedding score seen in FPHL (p<0.0001).

A visual analogue scale to assess female hair loss that is related to increased hair shedding is described. This tool was only studied in women and girls with long and shoulder length hair, as women in the pilot group with short hair found the scale difficult to use.
Data from the pilot study indicated that women can reliably self-score hair shedding.
Data form school girls with a mean age of 13.51 years, among whom androgenetic alopecia would be rare was used to define normal hair shedding as stages 1, 2, 3 or 4 for girls with long hair. Girls with short hair were not studied. Long hair is very much in fashion for adolescent school girls in Australia and girls with short hair are currently difficult to find.
A new visual analogue hair shedding scale accurately defines normal and abnormal hair shedding in females with long hair (Figure 1). Grades 1-4 can be considered normal for women with long hair. Grades 5 and 6 shedding indicate excessive hair shedding in women. Excessive hair shedding is found in 68% of women with FPHL who have long hair.

Example 2
Assessment of the safety and effectiveness of a single once daily oral capsule containing minoxidil 0.25 mg and spironolactone 25 mg in the treatment of FPHL.

Methods
Women with a Sinclair stage 2-5 female pattern hair loss were offered treatment with a single once daily capsule containing minoxidil 0.25 mg together with spironolactone 25 mg. For women with a baseline blood pressure ≤ 90/60 or a past history of postural hypertension or fainting 50mg of sodium chloride was added to the capsule. Hair shedding was scored using a visual analogue scale (figure 1). Hair density was scored using the 5 stage Sinclair scale (Messenger et al. 2010). Women were reviewed at 3 monthly intervals. Blood pressure was recorded at each visit and patients were specifically questioned about the presence of unwanted facial or body hair at each follow-up visit and any other side-effects.
Full blood count, renal function, electrolytes and liver function testing was performed at baseline and at 3 monthly intervals.

Results
100 women with newly diagnosed Sinclair stage 2-5 female pattern hair loss were treated with a once daily capsule containing minoxidil 0.25 mg and spironolactone 25 mg and followed prospectively for 12 months.
The mean age was 48.44 years (range 18-80). Mean hair loss severity at baseline was Sinclair 2.79 (range 1-5). The mean hair shedding score at baseline was 4.82. Mean duration of diagnosis was 6.5 years (range 0.5 -30).
Side effects were seen in 8 of women but were generally mild. No patients developed hyperkalaemia or any other blood test abnormality. Six of these women continued treatment and 2 women who developed urticaria discontinued treatment.
Baseline mean systolic blood pressure was 122.92 mmHg. Baseline mean diastolic pressure was 79.17 mmHg. Follow up blood pressure after 3 months was 118.40 systolic and 72.69 diastolic. Mean change in systolic blood pressure was -4.52 mmHg. Mean change in diastolic blood pressure was -6.48. Patients (2) developed symptoms of postural hypertension necessitating introduction of 50 mg daily of sodium chloride.
Four patients reported hypertrichosis. This was managed by a combination of plucking, or waxing.
A temporary increase in hair shedding 3-6 weeks following initiation of treatment was anticipated. Twenty-two patients reported this shedding as being of significant concern. All patients had been pre-warned about the possibility of a temporary increase in hair shedding on initiation of therapy and advised to continue treatment. No women discontinued the treatment as a result of increased hair shedding following commencement of therapy. For 16 women this shedding ceased within 4 weeks, while for 4 women it persisted for more 6 weeks and for 2 women it persisted for more than 12 weeks.
Two patients ceased the medication due to urticaria that was presumed to be related to the spironolactone. The urticaria settled within 7 days of cessation and did not recur when the minoxidil was recommenced as monotherapy.
Mean hair loss severity at baseline was Sinclair 2.79 (range 1-5). Mean hair shedding score at baseline was 4.82.
Mean reduction in hair loss severity score was 0.1 at 3 months, 0.85 at 6 months, 1.1 at 9 months and 1.3 at 12 months (figures 2 and 3). Mean reduction in hair shedding score was 1.1 at 3 months, 2.3 at 6 months, 2.7 at 9 months and 2.6 at 12 months.
Once daily capsules containing minoxidil 0.25 mg and spironolactone 25 mg was well tolerated in the majority of patients with FPHL and is a reasonable alternative in women intolerant of, or unwilling to use topical minoxidil. While hyperkalaemia, creatinine elevation and hepatitis are reported with spironolactone, we did not encounter any haematological abnormalities at the dose used in this study. Most women noticed a reduction in hair shedding at 3 months and an increase in hair density at 6 months.

Example 3
Monilethrix is an autosomal dominant genodermatosis characterized by hair fragility and breakage, keratosis pilaris and pathognomonic beading of the hair shaft. An autosomal recessive variant is also reported. There is no satisfactory treatment for Monilethrix. We report two cases of Monilethrix, where treatment with oral minoxidil led to a significant improvement in hair volume and length within three months.
The gene for autosome dominant monilethrix has been mapped to the epithelial keratin gene cluster on 12q13, (Ven Steensel et al. 2005) and point mutations has been found in the hair cortex-specific keratin genes KRT86, KRT83 and KRT81 (Horev et al. 2003; De Cruz et al. 2012). Mutations in desmoglein 4 is responsible for autosomal recessive variant of monilethrix. Monilethrix demonstrates considerable inter-and intra-familial variations in age of onset, severity, and natural history (De Cruz et al. 2012). Most often, hair is normal at birth and is progressively replaced by short, fragile, brittle hair during first months of life. Hair breakage secondary to hair fragility may be accompanied by follicular keratosis most commonly on the occiput. Eyebrows, eyelashes, pubic, axillary and general body hair may be affected along with the scalp.
In most patients, the hair loss persists with little change throughout life. Spontaneous improvement or complete recovery has been reported during pregnancy. There is no curative treatment for monilethrix. Reduction in hairdressing trauma may diminish weathering and improve severely affected cases (Sinclair and De Berker 1997).

Methods
Patient 6: A 40 year old woman presented with lifelong fragile, sparse, and thin hair. She had been diagnosed with monilethrix in childhood and presented seeking treatment for her hair. She reported striking improvement in hair volume and length during each pregnancy; that relapsed twelve months post-partum. Comorbidities included Crohn's disease and impaired hearing. Her daughter and two sons had also been diagnosed with monilethrix and suffered from sparse and fragile hair. On examination, she had brittle, lustreless, fragile short hair all over the scalp. Her hair crumbled when rolled between our fingers. She was noted to have small keratotic papules on the nape of the neck. There were no nail or tooth abnormalities detected. Dermoscopy (Figure 4) confirmed the diagnosis of Monilethrix. As the application of topical minoxidil could potentially accentuate breakage of fragile hairs, treatment was commenced with oral minoxidil 0.25 mg daily.
Patient 7: A 35 year old woman with fragile, thin and sparse hair since childhood secondary to monilethrix presented for assessment and treatment. She had a positive family history of monilethrix affecting her son, daughter and grandson. Examination revealed brittle lustreless, fragile short hair all over the scalp, keratotic papules on the occipital scalp and keratosis pilaris. No nail or dental abnormalities were present. Dermoscopy showed elliptical nodes which separated by narrower internodes (Figure 4). As the application of topical minoxidil could potentially accentuate breakage of fragile hairs oral Minoxidil 0.25 mg daily was commenced.

Results
Patient 6: Review after six months revealed significant hair growth with reduced breakage and increased hair volume and length (Figure 4). The patient did not experience any side effects or complication of the treatment.
Patient 7: On examination three months following the initial consultation, hair shedding decreased significantly. However, the hair density remained unchanged. Minoxidil increased to 0.5 mg daily. There was a significant improvement in hair density on review at 6 months (Figure 4).
Oral minoxidil is a promising treatment for hair loss associated with Monilethrix. When used in low doses it appears to be well tolerated.

Example 4
Chronic telogen effluvium (CTE) may be primary or secondary to a variety of causes including drug reaction, nutritional deficiency and female pattern hair loss (FPHL). The objective of this study is to assess the treatment of CTE with once daily oral minoxidil.

Methods:
The goals of this study were to review the use of oral minoxidil in CTE with respect to the response to hair shedding and safety. Hair shedding was assessed by patient self-reported Hair shedding Scores (HSS) using the visual analogue scale as described in Example 1 and Figure 1. Hair Shedding Scores (HSS) were on the scale of 1 to 6 (6 being the highest level of hair shedding). Patients included in this study were women with a diagnosis of CTE based on > 6 month history of increased telogen hair shedding, a HSS of 4- 6, no visible mid frontal scalp hair loss (Sinclair stage 1) and no hair follicle miniaturization on scalp biopsy.
Data pertaining to dosage of oral minoxidil, previous treatments including topical minoxidil use, blood pressure, side effects, hypertrichosis and trichodynia were collected for each patient. Patient-reported responses were based on a visual analogue scale HSS at each consultation. The HSS prior to starting oral minoxidil, and scores at 6 and 12 months were extracted for analysis. Patients were treated with a once daily oral minoxidil (0.5 to 2.5 mg).
Data were analysed using Matlab R2014b statistical software. Hair shedding scores at baseline, 6 and 12 months were analysed using the Wilcoxon rank sum test for pair-wise comparisons. Differences in blood pressure at baseline and 6 months were also analysed using Wilcoxon rank sum test. Relationship between outcomes (HSS at six and 12 months) and individual patient specific variables including previous use of age, topical minoxidil, duration of disease, dosage and HSS at baseline were analysed using a generalised linear regression model.

Results
Thirty-six patients with CTE, who were prescribed oral minoxidil, were included in this analysis. The mean age was 46.9 years (range 21-83 years) and the dosage of oral minoxidil used varied between 0.5 and 2.5 mg with most patients being administered 1 mg. Mean baseline HSS was 5.63. Mean HSS improved at 6 and 12 months at 3.9 and 3.05 respectively (Figure 5). There was a reduction in mean HSS from baseline to 6 months of 1.7 (p<0.001) and a reduction in mean HSS from baseline to 12 months of 2.58 (p<0.001). Similarly, a mean reduction of 0.89 in HSS was noted between 6 months and 12 months (p =0.003). Correlation between the duration of disease and previous topical minoxidil with HSS at 6 months (R2 < 0.22) and 12 months (R2 < 0.11) were weak. Eleven patients had previously used 5% topical minoxidil. Of these patients the mean change in the HSS was higher, although not statistically significant, compared to patients who did not use topical minoxidil. Mean reductions in HSS for patients who had previously used and not used topical minoxidil were 2 and 1.56 (p= 0.22) at six months and 3.18 and 2.32 at 12 months (p=0.11). The HSS improved in 31 patients after 6 months; in 4 patients the HSS remained the same; and in 1 patient the score increased at the 6-month mark before improving, compared to baseline, at the 12-month mark. After 12 months the HSS remained equal or improved from baseline in all but 3 patients.
There were no significant differences between blood pressure at baseline and 6 months (p>0.05). The lowest blood pressure recorded was 90/70. All other patients in the study had a blood pressure above 100/70. Mean doses in patient groups based on the presence of side effects is presented in Table 3 (p -values represents significance of corresponding differences in doses). The 5 women who described trichodynia at baseline all noted improvement or resolution within 3 months. Mean change in blood pressure was minus 0.5 mmHg systolic and plus 2.1 mmHg diastolic. Two patients developed transient postural dizziness that resolved with continued treatment. One patient developed ankle oedema. Thirteen women developed facial hypertrichosis. For 6 women this was mild and did not required treatment. Four patients waxed their upper lip or forehead and three patients had laser hair removal. No patients developed any blood test abnormalities.

Table 3:
| Yes | No | p-value
Hypertrichosis | 1.46 mg | 0.99 mg | 0.07
Trichodynia | 1.19 mg | 1.11 mg | 0.75
All the patients in this study demonstrated an improvement at either the 6 month or 12 month mark, with 33 patients improved from baseline at the 12 month mark. This analysis of 36 patients from a single dermatology centre shows that low-dose oral Minoxidil may decrease hair shedding in women with CTE. Patients previously unresponsive to topical minoxidil may still benefit form oral minoxidil. The patient cohort experienced minimal side effects (dizziness and ankle swelling) which settled during the treatment.

Example 5
There are no FDA approved treatments for female pattern hair loss (FPHL). FPHL is the female equivalent of MPHL (Messenger et al. 2010). Female pattern hair loss most commonly affects the mid-frontal scalp (Olsen, 1999). A proportion of women with FPHL also have hair loss over the vertex scalp or bitemporal recession. Off label oral treatments for female pattern hair loss include the androgen receptor antagonists spironolactone, cyproterone acetate, flutamide as well as the 5 alpha reductase inhibitors finasteride and dutasteride (Messenger et al. 2010). While hair loss will be arrested in a proportion of women with these agents and regrowth over the vertex or mid-frontal scalp has been documented, regrowth of bitemporal hair loss is not reported with any of these agents (Messenger et al. 2010).

Methods:
Patients were treated for 6 weeks with oral minoxidikl 0.25 mg daily.

Results
We report 2 women with significant bitemporal recession occurring in the context of female pattern hair loss who noticed bitemporal hair regrowth after 6 weeks of oral minoxidil 0.25 mg daily.
Patient 8: is a 45 year old woman who presented with a 2 year history of increased HSS (stage 6), reduction in the thickness of her ponytail by 50%, and loss of hair density over her vertex scalp and bitemporally. Her blood pressure was 110/70. She had baseline facial hypertrichosis, necessitating plucking her chin and upper lip one a month. Baseline blood tests were all normal. She was commenced on minoxidil 0.25 mg. On review at 3 months, the hair shedding had reduced to stage 5. Her blood pressure was 115/65. Her facial hypertrichosis was unaltered. He vertex hair density was slightly improved, while her bitemporal hair loss was noticeably improved (figure 6). In addition her hair was noted to be slightly darker in colour. She reported no side-effects from the treatment when questioned.
Patient 9: is a 48 year old woman who presented with a 3 year history of increased HSS (stage 6) mid-frontal hair loss (stage 3). Over that time she had noticed a reduction in the volume of her ponytail by over 50%. She had been commenced on spironolactone 200 mg daily by a local dermatologist 12 months prior. Her mid-frontal hair density had stabilized, but she continued to have increased hair shedding, trichodynia and bitemporal recession. Her Blood pressure was 140/85. Treatment was commenced on minoxidil 0.25 mg once daily. She continued to take the spironolactone, albeit in the reduced dose of 100 mg daily. Review at 6 weeks revealed a reduction in hair shedding (stage 4) and the trichodynia had disappeared after 2 weeks and not returned. While there was only slight improvement in her mid-frontal hair density at 6 weeks, there was significant bitemporal regrowth (figure 7). Her blood pressure was 125/85. All baseline haematological investigations were normal. She had not experienced any side effects or complications of treatment and in particular denied any facial hypertrichosis or unwanted hair elsewhere on the body.
This is the first report of treatment for bitemporal hair loss occurring in association with female pattern hair loss with an oral medication.

Example 6
The objective of this study is to assess the impact of a single once daily dose of 0.25 mg oral minoxidil in AGA (androgenetic alopecia).

Methods
This study was a pilot, prospective, open, observational study conducted at the Sinclair Dermatology Clinic in Melbourne, Australia. Participants were dosed for 24 weeks. Treatment naive men with Hamilton Norwood staged III vertex, IV or V were treated for 24 weeks with minoxidil 0.25 mg once daily. The primary efficacy endpoint was investigators' photographic assessment at week 24 and adverse events. Investigator photographic assessment was conducted by a single investigator grading the photographs using a 3 point rating scale, ranging from "decreased hair growth" to "increased hair growth," centred at no change. Any reports of adverse events were collected at every visit. Full blood count, renal function, electrolytes and liver function testing was performed at baseline and at 3 monthly intervals.

Results
Six men were treated with oral minoxidil 0.25 mg daily and for 6 months. Mean age was 50.17 years (range 23-65). All 6 completed 24 weeks of treatment. Global photographic assessment showed an increase in the hair at the anterior and vertex scalp in all 6 patients (the patients are numbered 10 to 15, images of before and after 24 weeks of treatment are shown in Figures 8 to 10). No adverse events were reported. Low dose oral minoxidil 0.25 mg daily was well tolerated in all of our patients with MPHL.
